Scientists revealed an asteroid dubbed by some as a "city killer" came closer to the Earth than the moon this week.

科学家透露本周有一颗被科学家戏称为“城市杀手”的小行星距离地球比月球还近。

The Washington Post reported that scientists apparently had no idea it was coming.

《华盛顿邮报》报道称科学家显然不知道这颗小行星临近。

Asteroid 2019 OK came hurtling toward Earth at a speed of nearly 15 miles a second, before flying past.

小行星2019 OK以接近15英里/秒的速度飞奔向地球，然后从地球边掠过。

According to NASA, it was about 45,000 miles from Earth on July 25.

NASA称7月25日它距离地球约45,000英里远。

"It would have hit with over 30 times the energy of the atomic blast at Hiroshima," astronomer professor Alan Duffy told the Sydney Morning Herald.

天文学教授Alan Duffy对《悉尼先驱晨报》说：“撞击威力超过广岛原子弹爆炸能量的30倍”。

Duffy called the zooming space rock a "city killer."

Duffy将这颗超高速的太空岩石称为“城市杀手”。

Astronomers say it posed no immediate threat but they admit they had no idea the giant rock was headed our way, because it came from the direction of the sun.

天文学家说它并不构成直接威胁，但他们承认并不知道这个巨大岩石朝我们飞来，因为它来自太阳的方向。
